Embodiment Construction

[0050] Combine below Attached picture The present invention will be further described in detail with specific embodiments. like figure 1 As shown, a rotating vane type controllable speed dynamic steam-water separator consists of a separation cylinder part, a rotating separation part, a droplet collection and drainage part and a dry steam axial flow recovery part, wherein:

[0051] The separation cylinder part includes an inner sleeve 1 and an outer cylindrical sleeve 2. The inner sleeve includes an upper separation cylinder 1A, a middle separation cylinder 1B, and a lower separation cylinder 1C extending into the exhaust port of the high-pressure cylinder. Between the entire inner and outer sleeves between of ring section, like figure 1 Shown is the separation chamber 12; the upper end of the upper separation cylinder 1A extends to the exhaust port of the high-pressure cylinder, and the upper end forms a trumpet tube form. The specific function of this form is: due t...

Abstract

The invention discloses a rotary blade type dynamic steam-water separator with controllable rotational speeds. The rotary blade type dynamic steam-water separator comprises a separation barrel portion, a rotary separation portion, a liquid drop collecting and draining portion and a dry steam axial flow recovery portion. The separation barrel portion comprises an inner sleeve and an outer sleeve, the inner sleeve comprises a first portion, a second portion and a third portion, the first portion is an upper separation barrel which extends into a steam exhaust port of a high-pressure cylinder, the second portion is a middle separation barrel, the third portion is a lower separation barrel, and the rotary separation portion comprises blades, an impeller hub, a driving motor and a speed regulating device; the liquid drop collecting and draining portion comprises a separation chamber and drainage holes, and the drainage holes are formed in the lower portion of the outer sleeve; the dry steam axial flow recovery portion comprises axial flow recovery blades and a tail flow central post. The rotary blade type dynamic steam-water separator has the advantages that excellent separation effects can be realized without reducing wet steam speeds to a great extent, and accordingly spatial requirements can be lowered; water can be effectively extracted and separated under the dynamic control, and optimal separation effects can be realized for small-diameter water drop.

Description

technical field [0001] The invention relates to the field of steam-water separation of nuclear power steam turbines, in particular to the steam-water two-phase pre-separation of the wet steam discharged from the high-pressure cylinder of the nuclear power steam turbine. Background technique [0002] The inlet steam of the wet steam turbine in a light water reactor nuclear power plant is nearly saturated wet steam. After expanding and doing work in the high-pressure cylinder, the humidity of the steam at the exhaust outlet of the high-pressure cylinder is as high as 10% to 12%. If the steam with this humidity directly enters the low-pressure cylinder to expand and do work without treatment, the humidity of the final wet steam of the low-pressure cylinder will further increase to 20%~24%. [0003] The connecting pipe between the high-pressure cylinder and the steam-water reheater has been operated under wet steam conditions for a long time, which has caused serious corrosion / e...
